This event has been cancelled for 2020 due to C
OVID.

\n

The Astronomy Festival on the National Mall is the largest
annual astronomy outreach event in the United States and will take place
on the National Mall between 3rd and 4th streets on Sat. June 20\, 2020.<
/h3>\n

Cloudy skies and a 10-20% chance of precipitation this evening means
that the Crockett Park Public Night is again canceled.

\n

Although th
e Clear Sky Chart[1] predicts only 10% cloud cover at 21:00 local time\, m
ost forecasts [2][3][4] show mostly cloudy skies with a significant chance
of precipitation through this evening. Transparency prediction ranges fro
m POOR to TOO CLOUDY TO FORECAST. Not a good night for star gazing.

Weather forecasts force cancellation of our Public Night again. The
Clear Sky chart[1] predicts transparency and seeing mostly as “Too cloudy
to forecast”. As of 11:00 local time\, all the other forecasts [2][3][4]
predict mostly cloudy to overcast skies with a 15 to 50 percent chance of
a thunderstorm or rain. Conditions won’t be suitable for astronomical ob
servations.\n

The public night scheduled for 18 November is canceled. Although th
e Clear Sky Chart[1] currently says only 50% of the sky will be covered by
clouds\, all of the other forecasts predict “cloudy”[2] or “mostly cloudy
”[3][4] with a chance of precipitation. DC television weather-guessers al
l agree it will be mostly cloudy tomorrow evening with differing opinions
on the timing and amount of precipitation.\n

A
ll of the weather forecasts agree that cloud cover will increase after 15:00 to ‘mostly
cloudy’ (or worse). Transparency “too cloudy to forecast” and seeing poor to impossib
le won’t allow us to show the public wonders of the night sky.

All of the weather forecasts agree that Saturday evening will be c
loudy. They disagree only on how early rain will begin. Not suitable con
ditions for observing the night sky so tomorrow’s public night is canceled
.

\nAlthough the Clear Sky Chart shows only 20 to 40% cloud
cover[1]\, the ClearOutside site predicts over 80% of the sky obscured by
clouds.[2] WeatherUnderground says 39 to 70%[3] and AccuWeather says ~90%
cloud cover.[4] Other paid weather-guessers predict partly or mostly clou
dy and most give a five to fifteen percent chance of measurable precipitat
ion. Not conditions suitable for star gazing.\n

The June Public Night at C. M. Crockett Park is canceled due to cl
oud cover. C
learSkyChart predicts only 40 to 80 percent of the sky obscured by clouds but all of th
e other weather forecasts predict 90% or more coverage. Most also forecast a significa
nt chance of precipitation. Not a suitable evening for stargazing.

Public Night at C M Crockett Park for 3 August 2019 is CAN
CELED.\n

Weather forecasts are inconsistent but none are good. Clou
d cover predictions vary from 26% covered to 90%. Precipitation chance fo
recasts range from zero to 43%. All agree humidity will be an issue with
dew points just 1 to 3 degrees below air temperature. We don’t want to di
sappoint members of the public or risk optics and electronic mounts being
caught in a stray shower or thunderstorm. Tough call this time. \nPlease read the C.M. Crockett Page for park
details.\n
